JOHN W. IVALSH, OF TROY, NEW YORK, A SSIGNOR OF ONE-HALF TO ERASTUS IL-VAUGHN, OF SAME PLACE.

RAI LWAY- RAl L'FJOINT.

SPECIFICATION forming part of Letters Patent No. 41 1:2079, dated November 12, 1889.

Application filed February 11, 1889. Serial No. 299,542. (No model.)

' To aZZ whom it may amcc'rn:

Be it known thatI, JOHN W. WALSH, a resident of Troy, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Railway- Rail Joints; and I do hereby declare that the following is a full, clear and exact description of the in vention, that will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

My invention relates to improvements in rail way-rail joints; and it consists of the novel construction and combination of parts hereinafter described, and pointed out in the claims, and is an improvement upon the mechanism described in my prior applicaiion, filed in the United States Patent Oflice, December 15, 1888, No. 293,744.

Figure 1 of the drawings is a top plan View of my improved joint, one rail being shown in position by solid lines and the other rail being indicated by dotted lines. Fig. 2 is a vertical cross-section of the rail, taken on the broken line m x in Fig. 1, and showing my improved device in end elevation. Fig. 3 is a longitudinal vertical section taken on the broken line a; min Fig. 2. Fig. 4 is a top plan view of the flanged chair detached from the other parts. Fig. 5 is a bottom plan view of the detachable rail-sustaining slideplate and slidehooks or clamps integral therewith. v

In my said application No. 273,744: the railsustaining slide-plate was provided with a beveled slide-block adapted to fit and slide in an aperture in the base-plate of the railchair, which aperture had side walls beveled to correspond with the beveled edges of the slide-block. The dovetail contact of the bev eled edges of block and chair served to secure the slideplate firmly upon the chair during its slide movements to and from the rail.

In my improved device, which forms the subject of this application, I secure the slideplate to the base-plate of the chair by means of hooks or clamps fixed upon or integral with the slide-plates, so as to inclose the edges and fit the space between the ball and flange of the rails B, as shown in Fig. 2, B being the ball, and B the flange of the rail. The chair is also provided with a rib or flange A nearly parallel with the flange or plate A and with the open-ended slots A located in opposite sides of the chair-plate, adapted to receive the hooks or clamps C, integral with the railsustaining slide-plate C, also adapted to enter and fit the space between the ball and flange of the rails, as shown in Fig. 2.

The operation of the device is as follows:

The chair is placed upon a cross-tie, (represented by the broken lines T,) and the contiguous ends of two successive rails in a rail- Way laid thereon, as indicated partly by dotted lines in Figs. 1 and 3. The slide-plateis then placed upon the base-plate of the chair in a position such that its clamp-hooks C pass down through the slots A in the base-plate and the rail-sustaining plate 0 is parallel with the rails. The rail-plate C and its hooks are then slid toward the rails to about the position shown in Figs. 1 and 2 and the wedge D inserted in the space D between the flange A and the contiguous edge of the slide-plate, as shown in Fig. 1. The wedge may then be driven farther into the space D, thereby forcing both the rail-su staining plates or flanges C and A tightly against. the rails and wedging them in between the ball and flanges of the rails, thereby not only forcing and holding the rails in alignment with each other, but materially assisting the webs of the rails in resisting lateral strains.

The clamps O serve to bind the slide-plate and chair firmly together, while the wedge D serves to bind the same parts firmly against the rail, as fully described in my said prior application, thus nmintninin e' a joint nearly as rigid as though the chair, slide-plate, and rails were all one solid piece of metal.

\Vhat I claim as new, and desire to secure by Letters Patent, is

In a railsv y-rnil joint, n mil-supporting chair provided on one side with a raitsusmining flange or plate and on the opposite Side with a Wedge-retaining flange, which flanges are connected by a bnseplate havingopen-ended slots in its opposite edges contiguous to the wedge-retaining flange and forming a slideway for the slide-plate, in combination with a rail-sustaining slide-plate movable to and fro between the flanges on the chair and provided on opposite sides with base-plzrte-engaging slide-hooks or clumps adapted to enter the open-ended slots, substantially as described.

In testimony whereof I have hereunto set 20 my hand this 15th day of J nnunry, 1889.

GEO. A. MosHER, W. II. I'IOLLISTER, Jr.

It is hereby certified that the grant in Letters latent No. 145,079, issued November 12, 1889, unon the application of John W. Walsh, of Troy, N. Y., for an improvement in Railway-Bail J oints, was erroneously made to Erastus H. Vaughn, as assignee' of the entire interest in the patent; that said Letters Patent should have been granted to said John W. Walsh and Erastus H. Vaughn, jointly, said Vaughn being assignee of one-half interest only, as shown by the record of assignments in this offioe; and that saidLetters Patent should be read with this correction therein that the same may conform to the record oi the casein the Patent Office.

Signed, countersigned, and sealed this 26th day of November, A. D. 1889.
